(01. 91-445) .My present invention has referenceto a new between the wells there are reverselyarranged and novel construction of ink pads for applying conical portions in the nature of cores, but as ink to rubber stamps or the like, and has for its these cores are designed to seal the wells I will primary object the provision of a pad for this purhereinafter refer to the same as plugs.

The pad is to be forced into the wells so that the said plugs formed from a rubber composition that renders have a plunger action upon the ink in the well the same soft and non-porous and likewise renders to cause a desired quantity of the said ink (in 5 the same elastic and, therefore, susceptible of exaccordance with the pressure exerted by the pansion and contraction. The elasticity of the stamp on the pad) to fiow through the wells pad also serves to hold the same in its normal onto the outer surface of the pad and thus pershape.

The wells being vals, is slitted, cut or otherwise formed with subsealed by the plugs prevent the liability of the stantially conical portions that afford wells 2, and eengealihg f t e k in t Wells and the Consequent clogging of the wells is thus eilectively prevented. Furthermore, the device can be arranged upside down and the plugs will prevent the ink from flowing through the wells.

Having described the invention, I claim:

1. A stamp inking pad comprising a body of soft non-porous and elastic material having closely related ink wells entering from one face thereof, and a plug formed from the body in and sealing each well.

2. An inking pad of the type described, comprising a body of soft elastic and non-porous material having one of its faces slitted throughout at close intervals to provide cone-shaped ink wells and-cone-shaped plugs in and sealing the wells.

3. A stamp inking pad comprising a body of soft non-porous elastic material, having one 01 its faces provided with closely related series of in]: receiving wells, and a plug also of soft nonporous elastic material and having a portion fixed in each of the wells and said plugs normally sealing the wells, and said wells, when a pressure is exerted against the pad, adapted to have their mouths spread and the outer ends of the plugs likewise spread and forced into the wells to exert a piston action against the ink in the wells. p

4. An inking pad of soft elastic non-porous material provided with ink receiving conical wells, and an inverted conical plug also of soft 1 elastic non-porous material in and normally sealing each ink well.

5. A stamp inking pad comprising a body of soft non-porous and elastic material having closely related ink wells entering from one face thereof for the major width of said pad, and a plug formed from the body in each well, said plugs normally sealingthe wells and designed, when pressure is exerted thereagainst, to assist in spreading the mouths of the wells by entering the said wells and effecting a piston action upon the ink in the wells,
